You can get that not with any scale, but you need different sting gauges depending on the scale. As Explorer stated here, you might want to go in other specified threads as the String tension thread or maybe even the Tuning thread to get some more info.

i see alot of agiles that say, "Designed based on specs requested by our customers"
.......can i just tell them to make something and theyll produce it?? :P that would be awsome,
my idea-8 string multiscale 27-25.5, neck through, dual angled active pups, kalher trem,

^mmh it's not the first time I see ppl asking for a 25.5 - 27 multiscale guitar, so it might happen in a few production lines... e-mail kurt at rondo about it, and suggest that! its the best way to get your propositions somewhere they can become reality.
